研究了6种不同的栽培基质(泥炭+浮石:1:1,v/v;泥炭+珍珠岩:1:1,v/v;稻壳+浮石:1:2,v/v;粗砂+泥炭:2:1,v/v;土壤;椰子皮)对东方百合品种‘Siberia’和‘Vespucci’植株生长和花卉品质的影响。720个球茎被种植在穿孔的塑料板条箱中,放置在一个未加热的温室里。对培养基的理化性质进行了研究。该试验研究了开花天数、株高、花数、鲜茎重、叶片数和瓶插寿命。结果表明,与土壤相比,无土栽培基质对植物生长和花卉品质有显著影响。获得的值因基质类型而异。在泥炭+浮石中测定了最早开花时间(154.78 d)和最长株高(Siberia品种为120.82 cm),而在椰子叶中记录了最多花数(Siberia是7朵;Vespucci是5.67朵)和最大茎重(Vespucci是266.13 g;Siberia是353.91 g)。土壤栽培植株的瓶插寿命比无土栽培植株的瓶插寿命长。叶子的数量以稻壳+浮石(57.42叶)和沙土+泥炭(54.46叶)效果最好。

Kaynasli District in the western Black Sea region of Turkey has long been vulnerable to frequent flood damage due to the establishment of settlements within and around stream channels without regard to fluctuating peakstreamflow frequencies. The aim of this research was to determine the measures needed to protect the towns and villages from this type of damage. Daily total precipitation data for 1975–2010 were analysed, and rainfall-runoff models developed to estimate the potential yearly maximum discharge from each stream of sub-watersheds dominated by forests and/or agriculture. This was then calculated for different frequencies of the yearly maximum discharge. Flood analysis and mapping was modified via the one-dimensional Hydrologic Engineering CentersRiver Analysis System software to produce potential maximum discharge and geometric data for Kaynasli Creek. As the main creek of the sub-watershed, its crosssection was shown to be insufficient and incapable of containing the maximum discharge at the 100-year frequency presumed for the watershed, and subsequently was seen as having a high level of casualty risk. It was concluded that the one dimensional model could be useful, but 2D models were more suitable for these types of watersheds.

Titanocene alanine complex, Cp2Ti(O2CCH(CH3)NH3+Cl-)(2), has been found to have in vitro antitumor activity against Ehrlich ascites tumor cells. Study of the interaction between Cp2Ti(O2CCH(CH3)NH3+Cl-)(2) and DNA by UV-VIS spectra, fluorescence spectra, agarose gel electrophoresis reveals that Cp2Ti(O2CCH(CH3)NH3+Cl-)(2) forms a stable compound with DNA in molar ratio 1:1 and reduces the migration rate of ccc-DNA band and oc-DNA band. However, unlike cisplatin, the complex does not induce nicking of DNA even after a long incubation at a high ratio of the complex to DNA. The results suggest that titanocene-based antitumor agents have different mechanism of action from cisplatin-like antitumor agents.

Energy restriction is defined as reducing nutrient intake without dragging the organism into malnutrition. Energy restriction is preferred because it is a non-genetic intervention that increases life expectancy. Nicotinamide adenine dinucleotide(NAD~+)and adenosine monophosphate(AMP)levels, which are the indicators of intracellular energy deficiency, increase with energy restriction. The increase in NAD~+ level stimulates sirtuin(SIRT)enzymes, and the increase in AMP level stimulates AMP-activated protein kinase(AMPK). Various mechanisms are regulated by stimulating these enzymes. By Forkhead box O(FoxO)transcription factors, the ability of resistance to oxidative stress increases, and antioxidant genes, DNA repair, and autophagy genes are stimulated. Apoptosis is induced by stimulation of the p53 protein, and tumor growth is suppressed by the disruption of aging cells. The suppression of phosphoinositide 3-kinase(PI3K)-/-Akt, and therefore mTOR signal stimulates autophagy and mitophagia, and cleanses damaged cells and organelles. Mitochondrial biogenesis is stimulated, antioxidant capacity increases, and inflammatory response decreases. Adipose tissue and lipid metabolism are regulated by the regulation of fatty acid synthesis and oxidation. As a consequence, the effects of caloric restriction on cellular metabolism are regulated through the genetic pathways.

The excess vacancies in ternary CuZnAl and Ti-doped CuZnAl alloys quenched from temperatures between 673 K and 1223 K, and the behaviour of the quenched-in vacancies on postquench aging in martensite phase have been studied by Doppler broadening measurements. It has been found that adding Ti to the alloys results in the formation of vacancy-Ti solute atom complexes which lowers the mobility of the vacancies. In the Ti-free alloy, the prominent changes in the lineshape S-parameter during the early stage of martensite aging have evidenced the occurrence of vacancy migration to sinks, clustering or vacancy. related atomic distortion. The role of the vacancies in martensite stabilization has been discussed.
